Do You Need an EIN for a Miller Trust in Missouri?

Missouri's 886-4657 form and its instructions are silent on a tax ID — there is no EIN field anywhere on the form. As a trust composed only of the beneficiary's income under 42 U.S.C. § 1396p(d)(4)(B), a Missouri QIT is generally opened using the beneficiary's own Social Security number rather than a separate EIN, the way most grantor-type income trusts work. A branch may still ask for an EIN out of habit; if it does, keep the account titled in the trust's name using the beneficiary's Social Security number, and ask the branch to escalate to its trust department rather than forcing an identifier the form does not call for. Confirm the exact identifier with your bank and, if you have questions about the trust's tax treatment, a tax professional. That is the rule for a Missouri Qualified Income Trust. The question comes up most often at the bank, where staff may ask for an EIN out of habit. Below is what applies in Missouri and what to do if a branch's requirement differs from what Missouri FSD publishes. This guide is informational only and is not legal or tax advice; for your specific situation, consult a qualified professional.

Why the bank may still ask for one

Even though Missouri FSD does not require it, branch staff often ask for an EIN out of habit, because most trusts they open need a separate tax ID. If that happens, keep to how the account is titled under Missouri FSD's guidance, and ask for the bank's trust department if the first person can't help.

Either way, the account is an ordinary bank account

Whether or not an EIN is involved, a Missouri Miller Trust account is a plain dedicated checking account titled to the trust — not a special product. What trips families up is rarely the tax ID; it is the branch's unfamiliarity with the account type. Knowing the answer before you go keeps the EIN question from turning into a wasted trip.

The EIN question almost always surfaces at the counter. See what to say at the bank in Missouri for the other refusals families hit, and the full step-by-step setup.
